Sharp Corp has dropped the proverbial ball when it comes to manufacturing of display screens for Apple’s latest iPhone. According to Reuters, the Japan-based electronics company is having a hard time meeting demands due to the high cost of production.

With Apple’s rumored event announcement this coming Sept. 12 announcement, one has to wonder how Sharp will be able to “cut the mustard.”

An unnamed source told Reuters that Sharp has fallen behind in operations, but didn’t disclose just how far behind. The company has been one of a handful of display screen manufacturers for the iPhone for quite some time now. LG Display and AU Optonics are rumored to be back-up for Sharp’s lack of production. Both companies are also current display screen makers for Apple.

This is not the first time that Sharp has been on the naughty list for its inability to meet Apple’s requirements. The company was slated to manufacture display screens for the third-generation iPad. According to industry insiders, Apple rejected Sharp’s display screen in January due to the fact that it did not meet rigid standards for quality.

Apple is purportedly announcing a new product release in less than two weeks. Presumably, the company will reveal a new generation of iPhone (dubbed iPhone 5) and the widely speculated iPad mini. If the rumors are true, LG and AUO will need to be on top of their game for the production rush that is sure to happen over the next few months.
